Shared modes of presentation

What is it for two people to think of something under the same mode of presentation (MOP)? This has seemed a difficult question for “atomistic” theories such as the Mental Files approach or the Language of Thought hypothesis. Here I propose a simple answer. I first argue that, by parallel with the synchronic intrapersonal case, the sharing of a MOP should involve epistemic transparency between the token thoughts of the two thinkers. I then explain how shared words help bring about this transparency. Finally, I show how the account can deal with MOPs expressed using demonstratives and indexicals.
